All your advice is being written down in a Word file as a sort of doctrine to use when we'll get the back back out again I corrected the gaskets after the pic, they are sealant free though. New ones are on order, because the left side one has a nick in it. My dad has some Molykote A (final drive additive) left over from a Guzzi project he did last year, would that suffice? Trans rebuild should set us back 395 euros, not cheap but hey I don't want it to explode on us riding it. Duly noted, will correct that when the new intake rubbers arrive, thanks! The (non-smoking) Left side carb is at much less of an angle, that might explain why balancing the carbs in their current state was impossible lol. This one has more of an accidental slant Cheers for the insights! It is running rich in the right side and right now it doesn't need choke to start, so that says something about the state of the carb tune. I'm still waiting for new intake rubbers to replace the old cracked ones before I can really tweak the carbs to a better level. I wouldn't be surprised if it was the carbs all along, those bad boys can cause a lot of trouble. I ran it without the right side carb connected to the airbox and it still smoked under load, but we'll still check out the vent when the weather improves again. I thing my dad is learning the most here, he was swearing on the dual Bing setup, because he's used to a lone Amal connected to a British single. "These fuckers are hard to get right" I have some experience tuning Bings from my R45, the single biggest improvement I got with that one was new rubbers and new cables. Never had that one smoke on me, but it did smell like a refinery before overhaul.
